COP MOUNTING.

APPLICATION FILED SEPT- 21, 1920.

Patented May 10, 1921.

{ Reading, in the county of Berks and,

ennsylvania, have invented .certaln new WILLIAM: A. notion, or READING, PENNSYLVANIA. a p

p corounta ns;

aramie, f

\ knitting machines or the like, and it consists in improved means for supporting the unwinding thread so as to prevent any tangl ng orbreakage thereof, as fully described in connection with the accompanying drawing and clearly defined in the claims.

Figure 1 is a sectional elevation showing" the application of; my invention to a known cop arrangement indicated. I

F'g. 2 is a plan view ofone of thefour thread-supporting segment bars preferably employed.

Fig. 3 is a cross-sectional View of the cup on the line 22 of Fig. 1; showing the retracted positions of the thread-supporting bars though only one of them is fully illustrated; and indicating the operative position in dotted lines.

Fig. 1 is a fragmentary view looking in the direction of the arrow in Fig. 3, to show the spring employed to press inwardly upon the overlapping portions of two of the bars.

The drawing indicates an ordinary conical inner tube or quill 3 upon which the thread is wound, fitting upon a support 4 fixed to a central support-spindle 5, 5? in the base plate 6 so that its unwound lower end 7 below the woundthread indicated by lines 3 extends into an encircling cup. 8 on the base plate; this construction and arrangement being shown in my prior Patent No. 1,169,539.

The particular purpose of my invention is to provide such a support for loosened thread, underneath the winding 3, as will prevent its sagging and becoming entangled v and broken, as is ordinarilyliable to'occur. To this end. I arrange for tightly closing the small annular-space left between the inserted unwound quill end 7 and the wall of the cup 8, by means of a plurality of segment bars 10, as illustrated in Fig. 2; these being radially movable in the cup 8 so as to either bring the inner curve 11 thereof into close contact with the outer surface of the quill portion 7 during operation of the cop, as indicated by thedotted circle 11 Fig. 3 or Spcification of Letters I'atcnt. Application filed September 21, 1920.

' pins 15 se n No. 41174 6.

to bring the outer curve 12 thereof against the inner wall of the ring 25 in 'cup 8 so as Patentedtiaylo, 1e21 toeprovide space for introducing or withdrawing the cop.

Preferably foursimilar segmentbars 10 are employed, each provided with an inter-' mediatepivot hole 13 and with a shortarm 14L andea long arm 14 somewhat exceeding a quarter circle; :so that I when pivotally mounted infpalrs upon the operating pivottirely close the'annular space around the'unwoundiquill portion 7:, when they are swung sertion and withdrawal of the cop.

Each of the oppositely arranged pivotextends upward through enlarged open1ngs16 in the base plate 6 and the bot tom of the cup 8, and forms part of an -op-" erating'lever 17) pivoted at 18 to a bracket 19 under the plate 6. These pins are nor mally swung radially'inw'ard, as shown, by

a means of a spring 20, but are movable out- I Ward to the posltions shown in the drawing,

by merely pressing together the lever ends I 21. The segment bars 10, as previously stated, are swung inward and outward with pins 15, 15. hereafter referred to, their slightly overlapping arms 1 4,, 14 will enthey will provide annular space for free in- 1 the pivot pins 15, 15, being pivoted thereon and carried upon a flanged ring 25 'in the cup 8, as shown; e v, 1

The segment bars 10jare free to turn upon their intermediate pivot connections 13 to the pins 15, so as to adjust themselves to the respectivecurvaturesof the unwound quill oppositely extending portion 14 is made fixed to the flanged ring 25 and having an 1 upwardly turned end 31 Ias indicated in Figs.

3' and to normally press the longer arms 14 inward so as to equalize their contact 7 portion 7 and of the cup wall; but as the 1 v with the quill portion 7. The detail con-' struction specifically set forth may be readily '1 I modified within the scope of the invention as defined in the claims.

What I claim is:

cling the lower portion of said support;

said. cup, andthread-supporting bars radi- I i 1 1. In combination with a base plate carrying a central cop support and a cup enoirally movable, with said pins into and out of 7 contact with the lower portion of a mounted cop. V

2. In combination with a base plate carry-- ing a central cop support and a cup encircling the lower portion of said support; thread-supporting segment bars mounted in said cup, and radially-swinging operating levers for said bars pivoted below said plate and having bar-engaging pivot pins.

r 3. In combination with a baseoplate carrying a "central cop support and a cupencircling the lower portion of said'support;

' thread-supporting segmentbars mounted in said cup, operating levers for said bars pivoted below said plate and having bar-engaging pivot pins, and spring means for nor mally pressing said bars into contact with V the lower portion of a mounted cop.

4. In combination with a base plate carrying a central cop support and a cup encircling the lower portion of said support;

thread-supporting segment bars mounted in 7 ing a central cop support, and a cup encircling the lower portion of said support;

oppositely arranged radially movable pivot pins extending into said cup, four threadsupporting segment bars intermediatelypivoted in pairs upon said pins, and spring means for normally pressing said bars into contact with thelower portion of a mounted cop;

In testimony whereof I aflix my signature. 40
